Specification of Letters Patent.

Patented Nov. 9, 1915.

Application filed June 1, 1914. Serial No. 842,211.

To all whom it may concern.

' Be it known that I, FRANK E. WATTS, a citizep of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Carbureters,.of which the following is a specification, reference being had therein to the accompanylng drawings.

tion of the structure embodying theinvention; Fig. 2 is a plan view.

A; designates the engine casing, B the in duction conduit or manifold, and C the exhaust conduit.

D is the carbureter having the outlet E communicating with theinduction conduit and F is the air inlet conduit for the carbureter.

Various constructions have been employed to utilize the heat of the exhaust conduit for pie-heating the air supplied to the carbureter, but I have devised a simple and efficient arrangement and construction for accomplishing this result. Thus the air inlet conduit F for the carburetor is extended through the exhaust conduit and preferably is cast integral therewith. In the structure shown the carbureter, which is of the horizontal type, is positioned intermediate the exhaust conduit and the engine casing. This not only utilizes the heat of the engine and the exhaust conduit, but permits the carbu-' reter outlet to be attached directly to the engine casing while the air inlet G for the carbureter may be attached directly to the end H of the air inlet conduit F. Preferably the conduit F extends through the exhaust conduit at the junction I of the sev eral branches J,K, L and -M thereof, and the outerend provided with an enlarged chamber N having on the inner face a plurality of apertures O which are controlled by a'valve P.

What I claim as my invention is 1. The combination of an engine casing and the exhaust conduit, an induction conduit for the engine, a carbureter arranged intermediate the casing and the exhaust conduit having its outlet connected to the inlet of the induction conduit, and an air inlet conduit connected to the air inlet of the car.- bureter and extending through the exhaust conduit. I

2. The combination of an engine casing and the exhaust conduit, an induction conduit for the engine, a carbureter arranged intermediate the casingand the exhaust conduit having its outlet connected to the inlet of the induction conduit, an air inlet conduit and extending through the exhaust conduit, and a valve controlling the inlet of the air inlet conduit.

3. The combination with the exhaust manifold of an explosive engine, the same being formed with a plurality of branches leading to a common juncture, and with an air passage atthe juncture of the branches, of a carbureter at one side of the manifold having its air intake in communication with said air passage, and a valve mounted upon the other side of the manifold controlling the air-inlet of said passage.

4. The combination with an engine casing and a branched exhaust manifold, said casing being formed with an induction conduit, of a carbureter disposed intermediate the connected to the air inlet of the carburetercasing and exhaust manifold having its outlet connected. to the induction inlet, and an air supply conduit for the carbureter communicating with one end of an air passage formed in the exhaust manifold at the junc-.

ture of the branches, the other end of said passage being open.

5. The combination with an engine casing and a branched exhaust manifold, said casmg being formed \vlth an lnduction condult,

of a carburetor disposed intermediate the casing and exhaust manifold having its outlet connected to the induction inlet, an air supply conduit for the carbu-reter communicating with'one end of an air passage formed in the exhaust manifold at the juncture of .the branches, the other end of said passage being open, and means for regulating the volume of an entermg said air passage.

6. The combination with an engine casing and the exhaust manifold thereof, the casing 5 branches substantially alined With the inlet being formed With an induction conduit and tel-mediate the casing and the exhaust manithe manifold having a plurality of branches fold. leading to a common juncture, and having In testimony whereof I affix mysiguature an .au" passalge at the juncture of said in presence of two Witnesses.
